' Specification of Letters Patent;

Patented June '9, 1908.

Application filed January 25, 1908. Serial No. 412,582.

To all whom. it may concern:

Be it known that 1, DAVID S. KENNEDY, of borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines of which the following is'a specification.

My invention has reference to that class of line-casting or linotype machines wherein twoor more sets or fonts of circulating matrices representmg different type faces are stored ,in corresponding magazines, andthe mechanism so constructed that matrices from two or more magazines may be composed in a common line when so desired, as

shown, for example, in .United States Letters Patent No. 347,629. I In this class of mafor theautomatic stoppage of the distributing mechanism whenever'this occurs and to this end it consists in movably mounting members of the font distributing mechanism and connecting them with a distributer driving clutch in such manner that the lodged or impro erly placed matrices, acting on said mova le members, will cause the disengagement of the clutch and the stoppage of the mechanism. I

My improvement is susceptible of various modifications, which will suggest themselves to the skilled mechanic after consideration of this specification and the accompanying drawings; but for the purpose of illustration I have shown my improvement embodied in distributing mechanism of the character representedin ap lication of J. R. Rogers for United States atent, Serial 'No. 406,165,

with the exceptionfthat the matrices in the present instance are permitted, after being egjtrated, to passdownwardb k in 'vidualldistributersas in" atent 347,629.

Ihave the. drawings to those parts.-

resented in imgravity to the of the machine with which my improvements are immediately associated, and it is 'to be understood that all other partsmay be of theordinary or any suitable construction.

' Referring to the drawings, Fi re 1 is a rear elevation of the' primary dizitributing mechanism and adjacentparts.

Fig. 2 isa' vertical cross-section on the line 2-2, Figsl.

line the principal parts of'the mechanism and clutch connections. Fig. 1 4 is a vertical Fig. 3 is a perspective view showing in outlongitudinalsection on line 44 Fig. 2,.

illustrating the manner in which a lodged matrix effects the movement of the clutch controlling members. I I p Referring tothe' drawings: A represents the main frame Work, which may be of any form and construction adapted to sustain the other parts. Y

B, B, B etc. are the horizontal distributer bars along which the individual matrices are carried by the screws E, E, etc. and delivered into the up jfer ends of the vertically.

channeled throats C, etc. forming upward continuations of themagazines in which the matrices are supported; y

D, D, D etc. are a series of tubes, one for each magazine, leading downward 1n divergent lines from the primary .or font distribu-.

ter, and delivering the matrices to the ordinary mechanism, by which they are direct ed to mechanisms for feeding them to the respective distributers, B, B, etc. These feeding mechanisms may be of the character shown in United States Patent 848,7 71, or

of any other suitable construction, these parts forming no part of the present invention.

Passing now to the primary or font distributer to which my invention relates: F

represents the so-called distributor lift box into which the composed line of matrices is delivered horizontally, in an endwise direction, as usual.

G is the vertically reciprocating finger by which the matrices are lifted one after another from the end of the line in position to engage the teeth of distributer bar, H, overlying the tubes D, D, etc..

Each of the matrices, I, has its upper end formed with a V notch'with a series of 'distributirig teeth therein to engage" the corres onding teeth of the bar after the manner escribedin United States Patent 347,629.

Each matrix, except those of one font, is also 1 0 g provided in the lower end "with notches, the

matrices of different fonts having unhke notches, but all matrices of 'the same font being notched alike.

J, J etc. are horizontal screws lying adjacent to the distributer'in position to engage the edges of the elevated matrices in order to cause their movement along the bar H and over the upper ends of the tubes, D,D, etc.

The distribute'r'bar H has its teeth cut away at points directly .over the s aces be' tweenthe tubes D, fetc. in $110 manner that thejmatrices will cease to be supported by the bar while moving from'one tube to the,

'n'extthis that the .matrices may be ermitted to fall into the appropriate tu es.

In order to sustain the matrices, however, so that they may, while advancing, repeatedly rengage the teeth of the bar until they arrive over the tubes into which they should fall, bridges orsupports, K, K, etc. are located between the'uper ends ofthe tubes and beneath-the path of the matrices. These bridges have on their upper side horizontal teeth or ribs corresponding to the notches of the different fonts, so that as the matrices are carried forward one after another'they will ride upon, and be sustained by, the ribs and thus caused to repeatedly rengage the matrix arrives at the bri distributer bar at their upper ends until each correspond with-its notches. At such each matrix is permitted to fall astride of the ribs and to such level that its teeth cannot engage with-the distributer bar, so that on reaching the mouth of'the next tube, and ridingoff from the ribs, it is permittedto fall by-gravity through the tube in its course brid es,

This slidingblock is held normally in Operative osition by a spring, 1, as shown in Fig. 4. Y en the parts are actin in a normal manner it remains at rest; w en, however, a matrix, assuming an abnormal position, is carried by the following matrix forcibly against a bridge, as shown, for example, in Fi 4, the bridge and its supporting frame wil yield and move horizontally in the direction indicated by the arrows'for the purpose of throwing the driving clutch out of action.

Any suitable clutchf'or intermediate con' nections may be employed, but I recommend I the arrangement shown in 3, in which M represents alever centrally pivoted to the mam-frame with one end in osition to be acted upon by the sliding bloc L, while the mechanism, and in connecting ge the ribs of which point op osite. end'isconnected to a lever, N, centra' lypivoted to. themain-frame and acting in turnion the horizontal bar 0, which acts at oneend on the plate, P,-; turning about a armfota rock shaft, Q, turning on a orizontal axis and carrying-at its opposite end, an

arm, ,acted u on by a s ring, g, and controlliii g the clut dh, R,-thro 1 1gh which the distributin'g mechanism receives, motion, from a constantly driven pulley, S. The clutch and its-controlling device maybe of the form shown, or identical Withthose; used in com-- mercial linotypes of the present day. When?- odges against, orbetween, the

ever a {matrix bridges they yield and move the block, L, which, through the parts-abovedescribed, releases the clutch tripping devicegfli which immediately throws the clutchout of action. When the arm, g, is disengaged from the clutch the parts resume their original position and the distributer will continue its action.

The essence of my invention lies in movably mounting the bridges or detector lates, H, which form apart of the distri uting with the-movable bridges means for contro v mechanism, so that the action of the primary distributer will be arrested whenever the matrices assume mproper positions therein.

While it is'preferred to. connectthe yielding bridges with the clutch controlled there,- by, the use of the bridges in the absence of such connection is advantageous in that impro erly lodged matrices are permitted to 'yie d or move to a limited extent, and in such manner as to relieve them and the adjacent parts from'excessive strains; A slight move ment of the bridge will frequently permit a lodged matrix to escape and continue its course. I I

It is to be notedthat in my mechanism the bridges through which the clutch is controlled are members of the distributing mechanism proper; that is'to say, they serve to deter mine the position of the assing matrices, and the points at which't e are released. It is also to be noted that the bridges are stationary under ordinary conditions, and that they are moved by the matrices only when the latter are in an improper position.

Having described my invention, what I claim is:

1. In a matrix distributer, variant stationary distributing members, mounted to yield under the pressure of abnormally laced matrices, in combination with distributer driving mechanism controlled thereby.

2. In a distributer, the yielding matrix sustaining bridges in combination with a distributer dgiving clutch controlled by the movement of the, bridges.

3. The, ribbed matrix sustaining bridges,
